Serum albumin functions as a carrier protein for steroids, fatty acids, and thyroid hormones, and is vital in regulating the colloidal osmotic pressures of blood.
- Soluble in water at 50 mg/ml
- Isoelectric point (pI): 4,7
Due to their free hydrophobic region fatty acid free albumins are used to solubilise lipids in tissue culture, and are also used as blocking agents in Western blots or ELISA applications. Globulin free albumins are suitable for use in applications where no other proteins should be present such as electrophoresis.
This protein is prepared by a modification of the Chen low pH charcoal method. Contains approx. 0,2 mg/g fatty acids.
